I was wondering how exactly you guys were timing your runs. I don't mean like when to start or stop, I'm talking about what tool or program you're using, and specifically how to get the most accurate timer.

I'd like to hear from the others as well.

I use WSplit while running solely to check my pace. For accurate timing, I use a video editor to add a timer overlay. (e.g. youtube video ID "yCu4EdUSsCs")

I tried to mess with auto-splitting, but couldn't get my head around it. :/
